<p>yeah, or maybe its a setting you can control from the debugger, that sounds right.</p>

<p>I think the only relevant crash here, that isn't inside LLVM itself, would be a stack overflow. we could try to make those nicer (if we don't already)</p>

</ul>
<p>So remember that when we need more information about an issue, like:</p>
<blockquote>
<p>a minimal, standalone example that shows the problem<br>
links to duplicates or related bugs<br>
if the bug is a regression (something that used to work, but no longer does), then a bisection to the PR or nightly that caused the regression</p>
</blockquote>
<p>we can just do <code>@rustbot ping icebreakers-cleanup-crew</code> and have some people helping us.</p>

</ul>
<p>This was leadup to the design meeting last week. General conclusion was that we should try to create a working group for triage, and spastorino and pnkfelix started talking about that this week.</p>
<ul>
<li><a href="https://github.com/rust-lang/compiler-team/pull/232" target="_blank" title="https://github.com/rust-lang/compiler-team/pull/232">Major changes template PR is waiting on team</a></li>

<p>This has stalled out a bit, we need to talk through how to finalize the process and ensure that things are actually moving forward.</p>

<p>We are starting to have a "Standard checklist" for new ICE-breakers groups! </p>

</ul>
<p>In general, we probably want to think about the working groups we'll be pushing on this year, and also a bit about different "categories" of working groups:</p>
<ul>
<li>task-focused, high priority groups (nll, async-await, maybe traits etc)</li>
<li>slow progress over time groups (const-eval, const generics?)</li>
<li>
<p>people who own a general code area or are pushing on a endless treadmill (diagnostics, triage)</p>
</li>
<li>
<p><a href="https://github.com/rust-lang/compiler-team/issues/248" target="_blank" title="https://github.com/rust-lang/compiler-team/issues/248">We should document what team membership means, responsibilities, and how to adjust</a></p>
</li>
</ul>
<p>This is mostly taking details from the compiler contributors RFC and putting them in a central place (forge).</p>
